Specification of Letters Patent.

To all whomit may concern:

any adhering fiber 'so that it may. be readily drawn into the picking tube or cylinder G by the air which is sucked in to the said picking tube or cylinder through the Gpenings 2'. The use of the cam and finger Is not absolutely essential to the effective operation of the device but it is ofassistance when the cotton for any reason adheres to Within the end of the king tube or cylinder G is snugly fitted short picking tube K so as to rotate with said picking tube or cylinder through contact therewith. The/tube K is formed with an inclined continuous groove m into which a pin L secured to the picking tube or cylin- .der G extends in order to, at times. impart a reciprocating movement to said tube K. As above stated, the tube K rotates with the picking tube or cylinder and practically forms a part-thereof but should thexteeth 7: carried by the tube encounter an obstruction when presented to the cotton boll of a nature to overcome the frictional contact between the tube and the picking tube or cylinder, the pin L immediately engages the wallsof the groove m and moves the tube longitudinally, back and forth, causing its. teeth to move in and loosen the cotton in the boll-and thus release the same and also release the teeth from the obstruction, Or-

dinarily the tube merely revolves with the I rear end thereof will be formed tight or closed so as to confine the entrance of the air to the forward end. The inner casing may or may not be used with the modification shown in Fig. 4, but in case it is not the blades F are made of a size to fit the cas ing C.

M is a handle attached to casing C wherev by the nozzle may be conveniently manipulated by the operator. In use the mouth of the nozzle is pressed against the cotton in the boll by the operator and the air suction draws all the free or loose fiber from the boll into the picking tube or cylinder G, the inturned teethaen theshort tube K in the meantime engaging the cotton and loosening it up and carrying it around until it is dislodged and carried back'in'to the picking tube or cylindenG by the air. In the event the teeth on t'ube K meet with an obstruction sufiicient to retard or stop the rotary movement of the. tube with the picking tube or cylinder G the pin L acts to reciprocate the tube and thus free the teeth from the obstruction- Bv reason of the rapid comprisin .ters Patent is:

1. A nozzle for a cotton picker, com rising a revolving conveyor tube; relatively short freely revolving tube carried by one end of the first revolving tube; picker teeth attached to the short tube; and means connecting the two tubes to cause reciprocation of the shorter one when abnormal resistance is encountered by the said picker teeth while the longer tube revolves.

2. A nozzle for a cotton picker, comprising a revolving conveyer tube; a relatively short tube carried by one end of the first tube; picker teeth attached to the shorter tube; an inclined, continuous groove in one of the tubes; and means in the other tube engaging the said groove to cause reciprocation of the shorter tube when abnormal resistance is encountered by said picker teeth while the longer tube revolves.

3. A nozzle for a cotton picker, comprising arevolving conv'eyer tube; a relatively short tube carried by one'end of the first tube;-picker teeth attached to the shorter tube; an inclined, continuous groove in the shorter tube; and means on the first mentioned tube engaging the said groove to cause reciprocation of the shorter tube when abnormal resistance is encountered by said picker teeth while the longer tube revolves.

4. A nozzle for cotton picking apparatus, a rcvolvingitube having spirally arranged bladcs attached thereto; a fixed non-revoluble casing surrounding said tu e and blades and spaced at one end from said tube to form an air port; a spider rigidly attached to the other end of the said casing; and a second non-rcvolublc casing opcn at one end and inclosing the first mentioned casing and fixedly secured in spaced rcla tion thereto by the spider at its open end and by the revolving tube at its other.

5. A nozzle for a cotton picker; comprising a revolving tube having s 'iirally arranged blades attached tbcrcto; a fixed nonrevoluble casing inclosing part of the said M tube and the blades and having a port at one end; a second non rotatiug casing in closing the first casing lll spaced relation at the other end about the revolving'tube en-' compassing the first mentioned casing andspaced therefrom to form an air passage;

and a spider connecting the open end of the oiiter casing with the inner casing adjacent to said bearing. 7

7. A nozzle for a cotton pit'ker, comprising a revolving 'tube having spirally arranged blades attached thereto; air ports in the said tube adjacent the said blades; a fixed non-revoluble casing having a bearing at one end for the ube adjacent the said air Copies of this patent may be obtained for end; a second" fixed non-revoluble casing open at one end and closed at the other end about the revolving tube encompassing the first mentioned casing and spaced therefrom to form anair passage; and a spider con- Witnesses GEO.
